Clean Well Pump Pressure Tank
Why It Matters
Incorrect pressure causes the well pump to short-cycle, dramatically shortening its expensive-to-replace motor life.
Quick Guide
- 1
Gather your tools and materials
You'll need: Tire pressure gauge, Air pump. Materials required: necessary materials.
- 2
Perform the clean well pump pressure tank
Check the air charge in your well pressure tank and verify it is within 2 PSI of the cut-in pressure. Safety note: Turn off well pump before checking pressure.

Verify and clean up
Check that the work was completed correctly and clean up your workspace. If if pump is short-cycling or pressure fluctuates widely, consider calling a professional.

Community Tips
The pressure tank's air charge should sit 2 PSI below the pump's cut-in pressure; most residential systems require 38 PSI when the pump activates at 40 PSI. Use a Shurflo Digital Pressure Gauge ($12-18) to verify the air charge, as undercharged tanks force the pump to cycle excessively and reduce its lifespan by 30-40%.
Never pressurize or depressurize a tank without first shutting off power to the pump and opening a faucet to relieve system pressure—failure to do so risks sudden pressure release that can damage the gauge or injure nearby occupants.
Renting a commercial-grade air pump runs $15-25 per day, but a DeVilbiss Portable Air Compressor ($60-90) becomes economical if you'll service the tank more than twice over five years, since annual maintenance checks are recommended for optimal efficiency. ---
